I agree with you on that one. Being young myself, I deal often with people of the same age and it is a truth.

In my opinion, respect to others is the reflect of self-respect.

Not just that, but also upbringing and the fact that respect and manners is simply an old fashioned thing that is for old people, not the youth of today with all the entitlements they seem to feel due to politically correctedness in the schools, etc.
